To all 'whom it may concern.'

Be it `known that I, .FRAN y citizen of the UnitedStates, and aresid'ent of'Vest Orange, county of Essex, and `State of New Jersey, have invented certain new and uselul Improvements in Control Mechanismffor PhonogTaphic Apparatus, offwhich Y the following-is a .speciiication My invention relates to control 'mecha nism for phO-nographic apparatus.

The present, invention includes repeat mechanism which can be applied toa phonograph alone, or control mechanism inaccordance with my invention maybe utilized fory simultaneously actuatingA a phonograph so asto cause reproduction of aportion of theV record to be"repeated,fa.nd also for con- 'trollingl the operation, as by starting and stopping Vthe same',vofmeans adapted to d1s play Yvisiblel characters or symbols corresponding to the sound reproduced from a phonograph record.

Y "In theaccompanying drawings an ernbodiment of my invention V,isv shown incontration only and for a'fordinga clear under-l standing'V of the invention, and not for limi?.

nectionV with' "a phonograph Aof i the' Pathe type, havingY applied ,thereto any attachment Y operated from the phonograph'motor Vfor the display of visible signals corresponding 'to`thel sounds `reproduced, "but it is Ato be understood that the same isby'way ofillustation othe invention.`

Means are; providedk coactilng with said toothed.v segment to move the tone-arm 13 andreproducer 14 backwardly over the recordfor a short distance in order tocan-se the Y phonograph to repeat the Vreproduction for an portion. ofithe record groove, and in` j thek form@ shownsuch by grasping the handle 23, substantially tov the position shown in Fig. 4i, the pawl` 20 engages4 one of the teeth 16.v and movesv thel tone-arm 13 and-reproducerdli backwardly,

thus causing a portion of the record groove to be again reproduced.- Spring means are provided forthrowing the lever 18', 'when released,l into a position where the pa-wl 20' is-out'offengagement with theteeth 164.* In the form shown a spring-pressed plunger 24 is provided and` serves the' purpose just named, as well as acting as aisto'pv toprevent undue movement-ofthe lever 18.H When the pivoted fat 19 and having a pivoted lever 18 hasbeen turned from the position shownin to that shownV iniFi-g.y 5, further yino-vement oi"I the 'lever y18 is prevented bythe plunger 24fwhich has reached the limitoits moti'onagainst thespring 24';

and'so serves fasv a' lstop for the leverV 18. i

When the lever 18 is released, while 'in contact-'with the plunger 24, the plunger 24,

under the action ofthes'pring 24, turns the position in ,which the `lever 18 backward to a pawl 20v-is no longer :in engagement with'` l 'Y the teeth 16:

'It will "beik seen that;V with, the v`repeat.1 at? reproducer 14 can be' swungbackward for the width'io-fa small number of record Vgroove'siat vany time that the reproduction ofportion of the record is desiredto be repeated, by the paw/120,011 lthe lever 181 making engagement withjon'eor another of the Vteeth l16. With fa,k phonograph ofthe j Pathe type, in whichahill and dale reco-rd of-'loomparatively great width is trackedJ aV Vrounded sapphire ball, lthere lis no occa? sionfor providing means for liftingthe,re-y

producer ofthe record and it is sufficient merely to provide means formoving the reproducer ,Macross the record without lifting the reproducer and with the .reproducing spherey or ball in contact therewith. With othery types ofv reco-rds, lifting means may be provided if desired, but such means are preferably dispensed with, particularly in the case of a phonograph and record of the utilized for controlling such., attachment, as by starting and stoppingI thesame, etc. If

such vtape or other displayxmember con-- tinuedto be fed 'along whiley the phonograph was repeating, the correspondence be-y tween :the V.characters being exhibited and the sounds reproduced would be interfered Y siblegtorutilizethe repeating apparatus for with, and the characters at the point ofexhibition would get ahead of the corresponding sounds `and would no longer be exhibited simultaneously with the reproduction of the corresponding sounds. I therefore have illustrated means'actuatedby thelever 18 'for stopping andr starting the feed mechanism for the display member, whereby, by

Vproper manipulation, the correct correspondence between visible characters. being exhibited and sounds reproduced may be maintained Y.and at the Sametime it is posrepeating reproluction from sections of the Y phonograph record as maybe desire-d.; i

A ping and starting the exhi portionsfof the reproducl VVtion from phonograph jre-cords. p

hlbiting device mayjeomprlse a framev25 re- I"Ilhe lmeans,for exhibiting vsuch' .visiblev characters is preferably arraiged as anat-'.- tachmentfto theAv phonograph and to be driven from i the `phonograph motor.

, p y Such attachment per se is no par-ty of the present invention, which is directed toV improvement V:

ofthe controlandoperatin means for stoplloition apparatus and for repeating The exmovably attached to {the'phonograph cabiy -net as by means of thumb-screws 26 passing ,through slots for openings in the arms`27, l27` l The Vtape 2.8; may?A carry visible charac- Y teisof ,any sort, as, for example, the words shownin- Fi'gg2 of the drawings, and Amay a `universal driveconnection at itsvk opposite ends. 4The shaft 36' isv carried'by a bracket adapted to be turned on Isuch pivot by suitable means, such as a* rod 40.' Rotation is imparted to the shaft 36 from a gear 41 operated by the phonograph motor and which engages a pinion-42 on the bracket 38. The bevel gear 43 turns with the pinion 42 and drives a bevel gear 44 on the shaft 36. It will be seen that upon turning` the bracket l 38 `upon its pivot 39, the pinion 42 may bc engaged with and Vdisengaged from the gear 41, and that when engagement is had. be; tween such pinion andgear, the tape 28 will be fed forward and that when the pinion is disengaged from the gear, the movement of the various driving elements, and therefore of the tape28, will be stopped and will not begin again until' the gear isengaged by the pinion. In Fig. 1 the pini-onv42 engages the gear 41, an-d in Fig. 5 these parts are l shown in disengaged relation.

According to the embodiment of the present invention shown, the operatingv means,

as the rod 40 is interconnected with and actuated by the repeat lever 18 of the phonograph. V'Such interconnection may be secured n various ways, but in the forni shownthe rod 40 is pivoted to the rotatable disk 45 as shown at 46. Means are-provided for rotating the disk 45, and in the form shown a rod .47, pivoted ati/48 tothe disk 45,Y is used for this purpose.As the various parts just referred to Varepreferably lo- Y I catedibelow the instrument board of a pho- V nograph, and the operating lever 18 is preferably located thereabove, av slot or opening 49 is. cut in thejinstrument board and an arm 50,r secured, to theV lever "18, extends therethrough. Such arm'50` sused to actuateuthef rod. 47V and preferably isV provided i with a lost motion connection therewith so that the rody 47^isin1ovedby ItheA leverV 1,8V only v`atandtoward the limits of movement of such lever 18. In the vform shown. thev arm v5() has a hole 51 thereinthrough which the ;rodl 47 passes, and collars 52 and 53 are provided on the rod 47,!one on eachside of thearm 50. In Fig. 31tlie arm 50 is shown ingconta'et with the collar 53', and in Fig.' 4 itisshown incontactwith the collar 52. Suchflost Vmotion connecting means as has just been described makes it possi-ble to utilize the` repeat lever 18v to lconnect and' disconnect the drive mechanism yfor the ribbon 28,.` 4'Ifhe arrangement is suchthat when the p Y tone-armvand reproducer are swung back be driven 'byfafeed vrolllon thewshaft29- whichfisoperated from, a shaft 30 through v gearsf3`1, 32,',and the shaft 301s in turn" drivenfrom ashaft 33 by means of bevel l gears 34, `35,1;` yThe-shaft .33 is driven fromra" shaft 36 through flexible orV universally opf-l Verable'drive'means such as a shaft k37 'having preparatory to repeating reproductionvof a se'ctionof theJ record groove, the'movement of,the ribbon 28 isf automatically y stopped, butythepawl 20 may be disengaged from the teeth 16- by 'movement ofthe lever 18 without restarting themechanism for feed" given japfurther movement manual manipulation to 're-start thefactuatingy means for the tape 28:,at v,thedesired time whenl the Y ing the tape 28andfthe lever 18 may be" sounds being reproducedcorrespond to the words or 'characters exhibited 4to view by the tape.

If, for example, with the parts as shown in Fig. 1, the machine is set linto operation, a proper correspondence having been secured between the characters exhibited and the sounds reproduced, such correspondence will normj'a'lly bevmaintained during the reproduction ofthe 'entire' record.' If, however,"a small portion of the record, as, for

example, that corresponding tothe pronun-f ciation 1 Hof a particularly diiiicult word, phrase or the like, is desired tobe repeated, the lever 18 may be swung into the Vposition shown in Fig. 5 and the pawl20 contacting. with oneof the teeth'V '16 ywill push Vthe re-A producer back far enough to secure a'repetition ofthe desired word, phrase or thelike,y

and the' arm 50 on theV lever 18 having` con- 1 tactedV with the collar 52 will have moved the rod 47 longitudinally, yturned the rotary member t0 the position shown in Fig. 5.

'and moved the rod 40 longitudinally, there-l by disconnecting the pinion 42 from the gear 41. Upon release `of the lever 18, the springpressed'plunger 24 will move it backward suiiiciently so thatthe pawl. 20 is' out of engagement with the teeth 16. .During the repetitionlof the portion of the record de- Y sired, the ribbon 28 may remain stationary,

the pinion 42vv being disengagedffrom the gear 41. When the' reproductionY has reached the proper point the tape may be started by bringingv the lever 18 farther back, whereupon the pinion 42 is brought in engagement with the gear 41 by the connecting means including the rod 40, disk 45 and the rod 47, the rod 47being moved longitudinally by the lever 18 through the larm 50 thereon makingcontact with the collar 53.'

The pinion m'ay be held or locked in engagement with the gear by the pivot bearing 46 of the rod 40 moving slightly pasti-a dead Center on the disk 45, as shown in Fig. 1.

It will 'be seen that when the lever 18 is moved forward or toward-the record disk,

- two operationsr simultaneously take place,

namely, the reproducer is swung backward somewhat on its pivot and the driving elev ments of the visible character kexhibiting apparatus are disconnected, that when the lever L18 is released itk will be automatically re turned by the plungery 24 to a position in which the pawl 20 does not engage the teeth 16 so that reproduction may takeplace freely, the visible character exhibiting device meanwhile remaining stationary," and i that when the lever 18 is then brought farl ther backward away from the record, the

A reproduction is not'interfered with, as the pawl 2O moves still farther away from the teeth 16', but at the same time the drivingk elements for the exhibiting device kare rbrought into engagement .and l the feeding movement of the exhibiting apparatusmay be re-commenced at the'proper stage of the sound reproduction so as to secure the simultaneous exhibition of visible characters andk reproduction of corresponding sounds, and that by means suchv as herein disclosed, a

v repetition ofany portion of the reproduw tion of therecord may be secured whenever desired,l the corresponding visible characters remaining stationary while the repeating is taking place, and that the operator may restore the Ymovement of the exhibiting device at `the stage where it was interrupted, after which it may proceed as before. l V

Itis to be understood that the apparatus,

shown for the purpose of illustration and n aording a clear understanding of my invention, may be changed in 'numerous vrespects v'within the scope of' my claims'without desoY be dispensed with, and similar modifications may be madein' various other features of the `apparatus illustrated.
